The calibre Unitas is one of the rarest movements International Watch Company from Schaffhausen ever produced. Only a few 100 of them were made. This particular piece was made on order for Isidor Heilbronner’s watch company Unitas in Munich. The distinguishing ¾ plate movement of Swiss design illustrates once more the strong influence and the success of the watch and clock factories in Glashütte.
